IMPROVEMENT IN WRENCHES.

Specification forming part of Letters Patent No. 120,304, dated October24, 1871.

To all whom it may concern:

Be it known that I, THOMAS D. MGBRIDE, of Philadelphia, in the county ofPhiladelphia and State oi' Pennsylvania, have invented a new and uselulImprovement in /Vrench; and I do hereby declare that the following is afull, clear, and exact description thereof, which Will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.

The figure is a detailed perspective view of my improved Wrench.

My invention has for its object to furnish an improved Wrench, whichshall be so constructed that it may be adjusted in different positionsto adapt it for turning,` nuts or bolts in difterent positions or in anyposition; and it consists in the construction and combination oftheparts ofthe Wrench, as hereinafter more fully described.

A is the head ofthe Wrench, upon one side of which are formed the jawsa? to grasp the nut or i bolt-head. The opposite end or part of the headA is made rectangular in form, and has holes a2 a3 (t4 formed in it toreceive the end of the handle B. The hole a2 is formed in the end of thehead A in line with the jaws al. The hole a3 is formed in the side ofthe head A at right angles with the plane ofthe jaws a1 and in the sameplane. The handle B is made With a set or bend near one end, as shown inthe igure, so that it may be as a straight or S-handle, as may bedesired. The holes a2 a3 a4 are made slightly tapering, as are also theends ofthe handle B, so that it may be tapped firmly int-o said holes.The head A and handle B are designed to be both cast so as to require nofitting, thus enabling the Wrench to be made at small expense. Thisconstruction enables the Wrench to be easily and conveniently adjustedto take hold of the nut or bolt-head Whatever may be its position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The head A a] a2 a3 a4 and handle B, constructedsubstantially as herein shown and described, to adapt them to be usedand adjusted in connection with each other, as and for the purposes setforth.
